The two algorithms, worked for 1911
- Western: the Anonymous Gregorian algorithm
a=11 b=19 c=11 d=4 e=3 f=1 g=6 h=23 i=2 k=3 l=2 m=0h + l − 7m + 114 = 139, and 139 ÷ 31 = 4 remainder 15: month 4, day 15 + 1. April 16- Orthodox: Meeus’s Julian algorithm
a=3 b=0 c=11 d=14 e=5d + e + 114 = 133, and 133 ÷ 31 = 4 remainder 9: Julian April 10. Plus 13 days: April 23
